Patent GB-669088-A (GB)
Title: A process of improving fibres and textiles produced therefrom
Filed: 1948-07-14
Abstract: Fibres and textiles produced therefrom which consist of regenerated cellulose, such as viscose artificial silk or staple fibre are improved by depositing and then further condensing in or on the fibre primary condensates of synthetic resins produced on the one hand from dicyandiamide (which may contain cyanamide as an impurity only) if desired together with urea and/or melamine and, on the other hand, from aldehydes, especially formaldehyde, under neutral or substantially neutral conditions, i.e. at a pH between 6 and 7. Preferably at least one part by weight of dicyandiamide is used to three parts by weight of urea.  The process may be carried out in the presence of small proportions of "cross-linking agents" such as ammonium salts of cyanuric acid or of barbituric acid, or ammonium thiocyanate.  The dicyandiamide employed may be pure or may be the crude product prepared by extracting commercial calcium cyanamide with hot water at at least 80 DEG  C.  The dicyandiamide in the extract contains approximately 3 per cent monocyanamide and 2-3 per cent urea as impurity.  The extract is freed from lime by precipitation.  With the aid of the process of the invention, dressings of a conventional kind, such as starch or gum arabic can be fixed on the textile material fast to washing.  Preferably, the fibrous material steeped with the primary condensate mixture, after an intermediate drying, is heated in a drying chamber or by infra-red or high-frequency heating to 130-160 DEG  C. to complete the condensation.  Preferably, also, the drying and the completion of the condensation of the resins in or on the fibres is carried out with the textiles in a tension-free condition, the textiles if desired being washed after completion of the condensation and again being dried free from tension.  In an example viscose staple fibre is impregnated with a solution of 0.4 kgms. urea, 4 kgms. of the dry residue of an extract of commercial calcium cyanamide prepared as above, 18 litres of a 40 per cent formalin solution neutralized with caustic soda, 0.4 litre of concentrated ammonia in 74 litres of water.  The impregnated fibre is then squeezed strongly, dried at about 80 DEG  C. and heated for 5 minutes to about 155 DEG  C. Finally it is drawn through a dilute aqueous solution of soap and sodium carbonate at 70 DEG C., rinsed with water and dried free from tension.  In another example viscose artificial silk is treated in a similar manner with an aquous solution of an extract of commercial calcium cyanamide, melamine, ammonium thiocyanate and ammonium lactate. The process improves the crease-resistance, handle, shrink-resistance and tensile strength of the textile material treated.  Specification 493,938 is referred to.

Filed: 1971-06-04
Abstract: 1357420 Electroluminescence MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 4 June 1971 [4 June 1970] 18946/71 Heading C4S A method for making a particulate material-3 capable of exhibiting a D.C. excitable electroluminescence comprises immersing a powder of ZnS, or of a solid solution of ZnS and ZnSe, or a solid solution of ZnS and CdS, in an aqueous solution having a Cu salt concentration of 0À001 to 0À1 mol./litre at 20‹ C. to 90‹ C. for 3 to 180 minutes, the powder being activated with Mn or a rare earth element preferably A.No. 58 to 70, thereafter washing the material with pure water, and drying. The Cu salt may be cuprous bromide, chloride, or cyanide; or cupric chloride, bromide, sulphate, acetate, nitrate, carbonate or cyanide. The process effects a change in the colour of the powder phosphor and produces a surface p-type layer whose thickness depends on processing conditions. HCl or (NH 4 ) OH may be added to cuprous chloride solutions to form water soluble complex Cu ion. Alcohol rather than water may be the solvent. Preferably particle size is <4 Á, with major part in the range 0À4 to 2 Á. A ZnS : Mn phosphor of specified component concentration, which also exhibits photoluminescence, is prepared by firing MnCl 2  and ZnS in inert gas while ZnS activated with rare earth is fired in an oxygenfree non-oxidizing atmosphere such as H 2 S. ZnS powder with a p-type copper sulphate is mentioned. In application to an EL device ZnS : Mn is mixed with an organic binder paste including 82% urea resin and 18 wt. per cent of solvent to form a phosphor paint. Binder paste to phosphor ratio may be 2 : 3. The coated plate is heated to polymerize the urea resin producing a 10Á phosphor layer. Electrode 2 may be tin oxide, electrode 4 of evaporated Al or colloidal graphite. Forming of the device is disclosed. Examples describe phosphor preparation, the coating process with specific materials and concentrations, and device fabrication with a forming step, including also ZnS with 0À1 mol. per cent He and 0À1 mol. per cent Li. Reference is made to photoluminescence of samples prior to immersion in aqueous solution.

MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Hirmann, J. ; 1, Vine Street, Hillside, New Jersey, U.S.A.) June 27, 1934, Nos. 19054 and 19055. Convention dates, Aug. 3, 1933 and Aug. 16, 1933. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 28, 1934.] [Class 39 (i)] The contacts on a valve cap or base are formed of flat nickel strips 217, Fig. 3, which lie on the surface of an insulating collar 213, passing through apertures 214 and through slots 216 at the bottom of the collars ; the ends 218, 219 of the strips are welded together to form lugs to which the lead-in wires 220 are welded. A stud 212 positions the base in a socket 230, Fig. 8, formed in two telescopic parts ; the base contacts 238 are in the form of strips with a resilient part 239 pushing the contact surface towards the centre of the socket, a bent part being received in a recess 244 of the socket to limit movement of the strip. Drain holes 245 and an upstanding flange 246 are provided on the bottom socket part. In a modification the base contact strips 232, Fig. 13, are wrapped round projections 317 on the collar 316, the bottom ends of the strips being joined for reception of the lead-in wires 325 the projections 317 extend down to cover recesses 320 formed in the returned flange of the base, slots 321 in the edge of this flange providing leads for the wires 325. The gaps between the projections 317 are asymmetrically arranged to position the base in its socket. This is formed with a metal cup 326, Fig. 17, carrying a plate 329 which overhangs the inner edge of the cup ; slots 339 in the plate correspond to the projections 317 on the base. The socket contacts 335 are held between the plate 329 and blocks 337 carried by the cup. When the base is inserted into the socket it depresses a spring- pressed disc 340 until the projections are below the level of the contacts 335 ; a " bayonetslot " turn is then given to the base and the pairs of contacts engage stops on the plate 329 limiting the movement of the base. The Specification as open to inspection under Sect. 91 comprises also valve bases having platelike contacts 21, Fig. 3 (Cancelled), which are attached to the insulating base 11 either by turning over the ends 17 of extensions of the contacts or by moulding in position ; the contacts may be made of one piece folded over or of two blanks placed side by side. Attachment lugs 18 for the leads are provided. The socket for this base has spring grip contacts 127, Fig. 10 (Cancelled), held on a plate 117 by tongues 121 ; a cover plate 116 protects these contacts when the valve is not in place, this plate having slots 114 to allow the base contacts to engage with the contacts 127 ; these are formed from a single piece of crossshaped material. A depression 116<1> in the plate 116 assists in positioning the valve when inserting in the socket. This subject-matter does not appear in the Specification as accepted.

Disc apparatus gear-wheels, grinding and trueing teeth of.-A machine for simultaneously grinding a number of circumferentially spaced portions of an article, such as the teeth of a gear, comprises an arbor 19, Figs. 1, 2, and 5, on which the work is held, and shaped grinders 80 rotatably driven in sliding carriages 38 by flexible shafts 36 from pinions 35 meshing with a crown-gear 27. The shaft 33 of one of the pinions 35 is extended to receive a driving-pulley 34. The gear 27 carries a gear 29 meshing with a gear 45 on a shaft 46, and drives, through a worm-wheel 48 and clutch 74, a shaft 48' and a gear train 49 .. 51. thus rotating a crank 53 and communicating, through a pitman 54, a reciprocation to a ram 16 carrying the arbor 19. A gear 73 on the shaft 48<1> transmits motion, through a gear 72, a clutch 88, a shaft 68, and a gear 63, to a ring-gear 62 carried by a stationary basin 31 nested in the crown-gear 27. The gear 62 is formed with a cam-ring 83, which engages adjustable pins 81 on the carriages 38 to feed the latter inwards on blocks 39 against action of springs 38'. The blocks 39 are angularly adjustable in grooves 41 in the basin 31. The work is given a step-by-step rotation through a worm-wheel 15 secured to a tubular driver 13, which is rotatably and slidably connected to the ram 16, the worm-wheel being driven from an intermittently-rotated shaft 93 splined to a disc 95 frictionally driven from the shaft 46 by a bevel pinion 91 and a friction disc 92 journaled on the shaft 93. Rotation of the shaft 93 is prevented normally by a weighted stop-arm 103, Figs. 1 and 3, contacting with a shoulder 102 of a cam 101 on the last of a train of gears 97 .. 100, the first of which is secured to the shaft 93. The arm 103 is removed from contact with the shoulder 102, on the recedence of the carriages 38, by the contact of one of the latter with a sliding-rod 110 operating a plunger 108 and a one-way pawl 105, which moves the arm 103 and then swings freely therefrom so that the arm may immediately move back into engage ment with the cam 101, thus allowing a small rotation of the shaft 93 and arbor 19. A treadle 21 operates an ejector rod 20, which engages and ejects the arbor 19. In a modification, the wormwheel and hence the work are given a slow continuous rotation and cylindrical grinders are used, the cam-ring 83 being replaced by a camring rotating at a higher velocity than the work and shaped to correspond to the face of the tooth to be ground.
